The AirTAC GR60025JF2TK AirTAC Air Pressure Regulator 1 in NPT is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT1" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR60025JF2TK is an AirTAC GR-series air pressure regulator in the largest size, 600, with a 1 in NPT port. It performs one job only: reducing and holding downstream air pressure, adjustable across 0.05-0.9 MPa (7-130 psi). This configuration is ordered with the embedded square gauge fitted on a psi scale, a reverse/check valve (code K) that holds the downstream setting when upstream supply is lost, and no mounting bracket - the GR body is also panel-mountable. As a pure regulator it has no filter bowl, no drain and no lubricator.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with optional low-pressure type, gauge scale in MPa, psi or bar, and bracket or no bracket. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing data from the datasheet for your application.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Installed at the drop from a plant air header to a production hall, holding a steady downstream pressure for every machine fed from that 1 in line.
Feeding large-bore cylinders that drive diverters, gates and pushers on a bottling or carton conveyor, with the check valve holding the set pressure if supply dips.
Mounted ahead of a manifold serving impact wrenches and clamps in a fabrication cell, keeping tool pressure stable across a shared 1 in feed.
Start with the port step: size 600 with a 1 in NPT port is the largest GR option, chosen when the line and expected air demand call for the biggest connection. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) adjustment range; the standard type covers this fully, while the low-pressure L variant (not this code) caps at 0.4 MPa. Choose the gauge scale you read on site - this unit carries the square gauge in psi; MPa and bar scales are orderable. The K code fits a reverse/check valve, useful where downstream pressure must be held if supply drops. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as catalogue options - this code is the NPT version. Bracket is omitted (J); add one if you want panel or surface mounting hardware. Flow is published as curves, not a single rated number, so send us your flow requirement and we will confirm sizing against the datasheet before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR flow as performance curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure and required flow and we will confirm the sizing from the datasheet on request before you order.
K fits a reverse/check valve. It lets downstream pressure hold against the regulator seat when upstream supply is lost or vented, preserving the set pressure on the equipment side - useful on lines where a supply drop must not dump the regulated circuit. The square gauge on this unit reads in psi; MPa or bar scales are available to order.
